SEER-LEY B. LYON, 0F LEXINGTON, KENTUCKY I CULTIVATOR.

To all 'whom it may con cern Be it known that I, SHnRLi-:r B.'Lvox, a citizen of the United States, residing at Lexington, in the county of Fayette and State of Kentucky, have invented new and useful Improvements in Cultivators, of which the following is a specification.

This invention relates to cultivators, and

"the particular object of the invention is to provide simple and improved means whereby the cultivating members may be raised from and returned to the ground without manual effort on the part ofthe operator by power derived Afrom the wheels of the cultivator. l y

A further 'object of the invention is to provide a simple and efficient attachmentwhich may b e readily applied to any ordinary type of riding cultivator and used in connection therewith for the purpose before mentioned of effecting adjustment of the cultivator meml.V "o

A further o t of the invention is to provide simple .and improved means wherebv the depth` tcwhich the cultivating impermitted to enter into the ground mayv be a ged and regulated.

With thesenn,..- other ends in view which ,will readily appear as the nature ofthe invention is better understood, the same consists in the improved construction and novel arr ement and combination of parts In the accompanying drawings has been however, understood that no limitation is necessarily made to the precise structural detailsv therein exhibited, bu'tth'at changesfalte'rations and modilications within the scope ofthe claims may be resorted to when desired. In the drawings, Figure 1 is a top plan equipped with the improved. attachment. Fig. 2 is a rear elevathe cultivating implements lowered.' Fig. 4 is a longitudinal sectional v iew from the ground. Fig. 5 is a sectional detail View showing particularly one of the adjusting leversifor regulating the depth of the cultivating implements. Fig. 6 is a sectional detail view, enlarged, showing par? ticularlythe actuating lever and the latch Speciiication of Letters Patent.` Application led April 18, 1913. Serial No. TGLBBS.

Patente-d Sept. 1, 1914.

Corresponding parts in the several figures are denoted b v like characters or reference.

Referring to the drawing, -l represents the arched axle, B, B, the wheels, C, the frame and D, the tongue of a conventional cultivator. I

E is the front arch with the limbs of which the cultivator beams F are connected in the customary or in any suitable and-convenient manner.

The improved attachment comprises brackets or supporting members S rising from the cultivator frame at either side thereof and affording bearings for a rockshaft 9 provided with terminal cranks 10. 'The rock shaft 9 is supported above the axle A and in substantially parallel relation to said axle and also in parallel relation to another rock shaft 11 which is supported below the first mentioned rock shaft 9 and which isactuated in one direction by means of a spring 12. Rack segments 13v which are secured on the rock shaft 9 are engaged by stop menibers 14 carried by hand levers 15, which latter are fulcrumed -upon the rock shaft 92 and the downwardly extended arms 16 of which are connected with the cultivator beams F by means of links or rods 17. The oscillatory movement of the rock shaft 9 in one direction is limited by means of an arm 18 that extends` radially from said rock shaft and is adapted to abut on the axle arch A of the cultivator. It will be seen that, the oscillatory movement of the rock shaft being thus limited, the extent of downw ard movement of the cultivator beams may be regulated and governed by proper adjustment of the hand levers 15.

Fitted loosely on the hub of each of the wheels B is a sleeve 19 having a radially exy tending arm 20 which is connected by a link orrod 21 with the crank 10 at the corre-` sponding end of the rock shaft 9. Each sleeve 19 is provided with another arm 22 extending radially at an angle to the first mentioned arm 20 and carrying a bell crank G, lone arm of which canstitutes a frame 23 carrying a roller 24'adapted to engage the teeth`of a ratchet wheel secured on the proximate cultivator wheel B. The other arm 26 of the bell crank is connected by a cord or chain 2T with a crank 28 at either end ofv the spring actuated rock shaft v11.

4The latter is provided with a radially extending arm constituting ay hand lever 29, wher-ebv it may be rocked against the tenico ^ by the bell cranks sion of its actuating spring, thereby actuating the lcell cranks Gr to throw the rollers 24 carried by the frame-like. arms of said bell cranks in engagement with the .teeth of the ratchets :25. The arm or lever 29 is formed with a catch 30 adapted to engage av stop arm 3lthat extends radially from the rock shaft 9.

When the arm or lever 29 is pressed. bythe. operator 'whose-.seat H is locatedv inrea'ryof.i the axle arch, the bell cranks -Grv Willbe'; actuated to place the rollers 24 carried there by in vengagement with the ratchetsi25 onthe 'cultivator wheels, by the rotation of which the sleevesY 19 will' be partly rotated With'the hubs of the Wheels, thus" causing the rock-1 shaft 9 to be oscillated bytheI connection be;

tween the arms 20 of the 'sleevesjl9 and the- 'termi'nal cranks 10 cultivator beams will thus be raised from the f ground by the rodsfor links'l' which' comiect.` said beams with the downwardly exten 'ngi arms 16 of :the hand levers 15. 'At' tlrel proper time,v the arin or leverf29'is releasedby the operator, and it'will now be in a forward direction by thetensionoithe actuating spring l2, placing thefcatch 30li1'1 the 'path of the stop ing the rock shaft 9 in its adjusted positiolhf 'While at the same time lthe rollers 24 carried; `G are released 'from -thej ratchets. 25. The cultiva'tor beams arethusi supportedV in d l .o rfor turningthe machine at the endrof the row.l AIn order to lower it is'only'necessar-topress the arm orflever i wheels and implement tion of the rock of the stop- 29 to disengage t fe catchO-om the step arm 31, when thec'u1tivatorbeam s'"`will def` until the' further rotation f scend by Gravity,` l of Vthe'roc shaft 9 is obstructed contact arm 18 with the axle arch; the extent of the descent being governed by pre- .vious adjustment of the hand levers 15', as hereinbefore described. v I f Having thusdescribed the invention, what is claimed as new, is:;A
